1998 Chevrolet Tahoe QuestionsWhy does my transmission not want to shift from 2nd to 3rd (1 answer)
Ok..so 1st thing I did is transmission tune up new filter, 2 selinoids , gasket and new fluid and no change.
What else can I check or so?
I changed practically everything that could be wrong with my heat but when I bought my truck the heater control valve had to be replaced but didn't have the money for it so I took it out and now I don't have heat at all.
